Question

The pressure exerted by a gas is 2.0 atm while it has a volume of 350 mL. What would be the volume of this sample of gas at standard atmospheric pressure?

Answer 1

700 mL or 0.0007 m³

Step-by-step explanation:

P₁ = Initial pressure = 2 atm

V₁ = Initial volume = 350 mL

P₂ = Final pressure = 1 atm

V₂ = Final volume

Here the temperature remains constant. So, Boyle's law can be applied here.

P₁V₁ = P₂V₂

`(P_1V_1)/(P_2)=V_2\\\Rightarrow V_2=(2* 350)/(1)\\\Rightarrow V_2=700\ mL`

So, volume of this sample of gas at standard atmospheric pressure would be 700 mL or 0.0007 m³
